Silicon Metal 553 Silicon metal 553 is a commonly used grade. In the metal silicon 553, the silicon content should be as high as 98.5%. The contents of iron, aluminum, and calcium are 0.5%, 0.5%, and 0.3% respectively.Silicon 553 and silicon 441 are mainly used in the production of aluminum ingots.Adding silicon metal to aluminium alloys makes them strong and light.

Silicon Metal 553 grade |
Silicon metal 553 generally the diameter is 10-50mm,50-100mm,10-100mm or other sizes as customer’s request.
Silicon metal is a gray and shiny semiconductor metal,also known as crystalline silicon or industrial silicon, is mainly used as an additive for non-ferrous alloys which smelted from quartz and coke in an electric furnace.
It is also known as non silicon alloy for industrial use. According to the content of Fe, Al and Ca in metal silicon, the metal silicon can be divided into 553、441、421、3303、2202、2502, etc. Metal silicon additional products include silicon powder, metal silicon slag, etc. Among them, silica fume is also called silica fume, micro silica fume, or silica fume, which is widely used in refractory and concrete industries.
The classification of metallic silicon is usually classified according to the content of iron, aluminum and calcium, silicon metal can be divided into different grades such as silicon metal 553/441/3303/2202 and 1101.
The chemical composition of metallic silicon is generally silicon, ferro, aluminum, and calcium. Therefore, the grade of metal silicon is divided according to the three main impurity contents of iron, aluminum and calcium.
For example:In the metal silicon grade 553, the contents of ferro, aluminum, and calcium are 0.5%, 0.5%, and 0.3%.
Commonly used grades are 553/441/3303/2202/411/421 and so on. What brand should be used specifically depends on what field the user is using and what effect he wants to achieve.

| Application |
1) Widely applied to refractory material and power metallurgy industry to improve the heat resistance, wear resistance and oxidation resistance.
2) In the chemical line of organic silicon, industrial silicon powder is basic raw material that high polymer of organic silicon formatting.
3) Industrial silicon powder is sublimated into monocrystalline silicon, which is widely used in highttech field as an essential raw material for integrated circuit and electronic element.
4) In metallurgy and foundry line, industrial silicon powder is regarded as to be iron base alloy additive, the alloy pharmaceutical of silicon steel, thus improve the steel hardenability.
5) These are used in high-temperature material production in order to manufacture enamels and pottery. These also cater the demands of semiconductor industry by producing ultra-pure silicon wafers.
